The AtlasIED UHT70C-U51-8 is engineered for life safety and emergency voice evacuation systems in commercial, institutional, and public assembly installations. Integrators and systems contractors specify this unit where UL 1480 compliance is mandatory, including schools, hospitals, office buildings, and transit facilities requiring fire-protective signaling loudspeakers.
This complete assembly pairs an 8" single voice coil driver with a dual whizzer cone and 10 oz. ceramic magnet for extended frequency response and high speech intelligibility across emergency alarm and voice instruction scenarios. The factory-mounted 70.7V transformer with multi-tap power selection simplifies distributed audio system wiring and allows contractors to optimize SPL and coverage without field modifications. The included U51-8 baffle delivers an unobtrusive ceiling appearance that integrates cleanly into commercial ceiling grids.
Fire-retardant and moisture-proof cone construction meets UL fire-protective signaling requirements, while the DC blocking capacitor and 6" color-coded leads accelerate installation and reduce wiring errors. The package must be installed with UL-approved enclosures to maintain UL compliance. A 60-month warranty backs long-term reliability in installed life safety deployments.
